Subject [jira] [Commented] (LUCENE-4764) Faster but more RAM/Disk consuming DocValuesFormat for facets
Date Tue, 12 Feb 2013 11:35:15 GMT


Shai Erera commented on LUCENE-4764:

Thanks for testing mike. So I guess FastCountingFA can go back to not specialize on this,
and this remains a faster DV format only?

And thanks for clarifying how those formats work. So I think that Facets42Codec can take a
FIP in the ctor.
